the county oi'. Albany and State lof New York, has i" vented certain new and useful Improvements in Railway-Ties, of which the following is aspecification.

My invention relates to improvements in concrete railway ties, and the object 'of my invention is to provide a reinforced concrete tie, so constructed that the rails may be moved from the positionin which they are first secured, when desired, and the spikes used for holding the rails may be driven into a tiepat any required point, together with such otherelements and combinations as are hereinafter moreparticularly set forth. I accomplish this object by means of the mechanism illustrated in the accompanying drawing, in

which: i

Figure l is an elevation. Fig. 2 is a longitudinal section. Fig. 3 is a plan. Fig. 4 is a horizontal section. Fig. 5 is an end elevation. Fig. 6 is a cross section along the lines A-B, on Fig. 1. Fig. 7 is a cross section along the lines CHI) on Fig. l.

Similar letters refer to similar parts throughout the several views. l i

It is often necessary in railway service to move the rails laterally, and for that reason I deem it advisable to have the material into which the spikes, used for holding the rails inplace,-are inserted to be such that they may be driven in without first drilling a hole, and for this reason, as Well as for the additional advantage obtained because of the less 2noise attendant in the passage of a trainthan when the rail is laid directly on. stone or concrete, I place a block, E, immediately beneath the rail and into which the spikes are driven.

Into a concrete tie,K, molded preferably in the form shown in Fig. l I place a small block, F, and resting thereupon I place a larger' block, E. The block, E, preferably, extends beyond the edges of the block, F, and is, preferably, provided with an offset, H, at each side, into which lit the upper ends of the Z-plates, I, I. The offset; H, being a suilicient depth from the upper' surface of the block, E, to cause the top of the Z-platc-s, J, J, when placed in' position to be flush with the upper surface of the block. The lower ends ofthe Z-plates, J, are embedded in the concrete and resting upon their horizontal end projections, j, j, respectively, I preferably place the short rods, L, L, which rods are also embedded in the concrete.`

The rail, M, is secured by the spikes, G, or other suitable retaining device, which may be driven through the block, E, into the block, F, and when desired the spikes may be Withdrawn and there is plenty of opportunity for causing them to again penetrate the block first occupied by it.A l f tfwill be readily seentliat 'the'lower block, F, need and retain the lrail in a position different from that -be of-very limited extent in each direction, since it is only necessary to make it large enough to receive the spikes, G, which, because of the nature of their use, d'o not require very great size to admit of such lateral change of tracks as is ordinarily necessary. The upper block, E, is larger,.not thick, and therefore the expense 'of these blocks is very small and their utility is such that they answer the same purpose that a heavy and expensive tie would provide. The lower block, F,being entirely protected from the weather and the elements would be practically indestructible, and the upper.

block, E, may be replaced when desired Without great difficulty or expense.

For the purpose of reinforcing the concrete I preferably place a s eries of rods, N, running lengthwise of the-tie, slightly separated from each other, and preferably placed near the bottoni of the tie, as shown-iin Figs. 6 and 7. These rods may be engaged at each end of the tie by a bail or handle, O, as shown in Fig. 5, which passes through a portion of the concrete so that it extends above the same, iorming'a means for lifting the tie into place.

I do not wish to limit myself to the location of the reinforcing rods, Nnear the bottom of the tie, with their ends extending diagonally toward the upper surlace and brought in contact with the bails, O, O, nor to the number of said rods, as these features may be varied without departing from my invention.

WhatI claim as my invention and desire to secure by Letters Patent is:

1. Railway rails; spikes for securing them to the ties; a railway tie comprising,T concrete, reinforcing rods therein; a wooden block embedded in said concrete; a wooden block larger than and resting upon said embedded block und secured in said concrete; said smaller' block so placed beneath the larger block that the spikes employed for securing said rails shall pass through the larger and into the smaller of said blocks.

2. In a railway tie comprisiuf.r concrete, reinforcing rods In testimony whereof I have aflxedilny signature in presence of two witnesses.
